Forensic automatic speaker recognition
Automatic speaker recognition technology appears to have reached a sufficient level of maturity for realistic application in the field of forensic science. However, there are key issues to be solved before the forensic community will accept its use as an investigative assistant or as evidence in actual criminal cases. To assess the state of the technology, the Federal Bureau of Investigation (F...
متن کاملPerformance Evaluation of Automatic Speaker Recognition Techniques for Forensic Applications
Speaker recognition is a biometric technique employed in many different contexts, with various degrees of success. One of the most controversial usage of automatic speaker recognition systems is their employment in the forensic context [1, 2], in which the goal is to analyze speech data coming from wiretappings or ambient recordings retrieved during criminal investigation, with the purpose of r...
متن کاملFM features for automatic forensic speaker recognition
Frequency modulation (FM) information from the speech signal is herein proposed to complement the conventional amplitude based features for automatic forensic speaker recognition systems. In addition to presenting the AM-FM model of speech used to generate the proposed frequency modulation features, the significance of frequency modulation for speaker recognition is discussed. Evaluation result...
متن کاملForensic automatic speaker recognition: fiction or science?
Hollywood films and CSI-like movies show a technology landscape far from real, both in forensic speaker recognition and other identification-of-the-source forensic areas. Lay persons are used to good-looking scientist-and-investigators performing voice identifications (”we got a match!”) or smart fancy devices producing voice transformations causing one actor to instantaneously talk with the vo...
